Stars move like dancers because of gravity. Imagine gravity as invisible strings pulling stars toward each other, some stars are pulled close, and others drift apart. Just like a ballet, the dance never stops, and it keeps going for millions of years.

Examples

  1. A ball falls to the ground because of gravity, just like a star is pulled toward another star.
  2. If you swing a bucket around your head, it stays up, stars keep moving because they’re being pulled by other stars.
  3. Two dancers move in perfect rhythm, two stars move in an orbit caused by their gravitational pull.
